Twin Cam Racers

[Ken Morton]

Where can I find the history of the three twin cam Austin Seven Racers?

Ken, I think you will have to consult several sources.

I would strongly recommend Geoff Roe's "Bert Hadley, a son of Birmingham", available from the PWA7C. An excellent book not only in relation to your interest.
Canning Brown's "Austin Seven Competition History" will cover a great deal.
Roland Harrison's "Austin Racing History" is well worth consulting.
Bob Wyatt's "The Austin Seven" will give you a useful basis for your spreadsheet.
If you have the indices to the A7CA "grey mags" you can find some useful articles.
Chris Garner will be along in a minute with the ones I've missed....

I can't think of a single specific history of the twin cams but, if there is, someone will soon tell us!

Regards,

Stuart

Thank you Stuart!
I think you've about covered them all. Geoff's book is excellent, as is Harrison's. With Canning Brown's you'll have to dig a bit.
It just depends Ken on just what information on the three cars you're looking for.

Not forgetting Martin Eyre's, 'Austin Seven Competition Cars 1922 - 1982

The film "The Pace that Thriills" shows the construction of the Twin Cams in some detail if looking for the internal details

Good stuff, Henry.
Am I right in thinking the Archives holds an original drawing of the Twin Cam engine? Mr. Archivist sir?

[Archivist]

You are correct Chris. These two drawings are thought to be by MJ himself....
